Forensic science represents the intersection of law and science, providing the analytical framework necessary to investigate crime scenes and resolve legal disputes. Advances in polymerase chain reaction (PCR) and next-generation sequencing have revolutionized the sensitivity and speed of analysis, allowing for the differentiation of mixed samples and the resolution of cold cases that were previously deemed unsolvable.
